Litigation: General Commercial | Canada

Ontario

This section ranks those firms and individuals which advise on civil litigation on behalf of businesses, high net worth individuals and other non-public sector entities. Judicial reviews, public inquiries, constitutional challenges, parliamentary investigations and other public body disputes are considered, as are broader disputes with public sector interest, including some municipal, privacy and extradition matters. Less weight is given to civil litigation types which are covered elsewhere in the Canada Guide, for example banking litigation, insurance or restructuring/insolvency. This chapter exclusively covers courtroom litigation, rather than alternative dispute resolution methods like mediation and arbitration.
